Morphology

quinone = quin + one

Formed from a specialized chemical combining form ('quin-') plus the chemical suffix '-one'; the root 'quin' is not a standalone English word and the compound meaning is technical, so an average B1 learner cannot derive the meaning from its parts.

Etymology

The word quinone comes from the parts quin- and -one, where -one is a chemical ending meaning 'a ketone', just like in acetone. So, quinone names a group of yellow organic molecules that have ketone parts and are used in dyes and in biology.
